Abstract: A load-energy efficiency evaluation and monitoring method includes an actual part processing number and a theoretical part processing number of the numerical control machine tool within an evaluation period are obtained to calculate a loading performance of the numerical control machine tool. A waste time value and a standby power value of the numerical control machine tool are obtained to calculate a waste energy value of the numerical control machine tool. A single-part actual processing energy consumption is obtained and used, together with a single-part ideal processing energy consumption, to calculate the load-energy efficiency of the numerical control machine tool. A relationship model between the load-energy efficiency and the loading performance of the numerical control machine tool is built based on the obtained model of the load-energy efficiency of the numerical control machine tool and the obtained model of the loading performance of the numerical control machine tool.

Abstract: An air preheating and denitration integrated reactor and reaction method. The reactor includes a rotary catalyst body, housing arranged outside the rotary catalyst body, and gas inlet and outlet channels on upper and lower surfaces of the housing; the gas inlet and outlet channel is in divided three, namely flue gas, reductant, and air inlet and outlet channels, the rotary catalyst body is cylindrical and includes a central shaft rotor and multiple circular catalyst layers rotate around the central shaft rotor, each circular catalyst layer is divided into air, flue gas and reductant zones by a radial sealing plate and axial sealing plate. In each circular catalyst layer, a catalyst in the reactor alternately circulates in flue gas, reductant and air zones. The catalyst performs heating-reheating-cooling process on catalyst layers along with the reactor rotation, different temperatures and reaction atmospheres in zones conductive of air preheating and denitration.
